NOYAFA NF-816LS Underground Wire Locator Instruction Manual

1. Okwu mmalite

The NOYAFA NF-816LS is an underground wire locator designed to quickly and accurately trace buried wires, detect cable breakpoints, and follow the direction of underground or in-wall cables. This device is suitable for various applications including pet fence cables, network cables, wall wiring, irrigation lines, and pipelines. It features a rechargeable lithium battery, an LED flashlight, and an upgraded "T-shaped" probe coil for enhanced stability and precision.

WARNING: Read all safety warnings and instructions before using this product. Failure to follow the warnings and instructions may result in electric shock, fire, or serious injury.

• This device is designed for single-stranded or parallel double-stranded wires. It is not suitable for multi-stranded wires or live testing.
• Do not use on circuits with a live voltage greater than 60V DC to avoid damaging the device or causing injury.
• Always ensure proper grounding when connecting the transmitter to a wire. Incorrect grounding can lead to inaccurate readings or device malfunction.

3. Ngwaahịa gafereview

The NOYAFA NF-816LS consists of two main units: a Transmitter and a Receiver. Key features include:

• Precise underground wire tracking and cable break detection.
• Upgraded "T-shaped" probe coil for stable and accurate positioning.
• Wide detection range: up to 2-3 feet deep and 1000 feet long (depth may vary).
• Rechargeable 3.7V 1100mAh lithium-ion batteries in both units.
• Ọkụ ọkụ LED arụnyere n'ime ya maka ọnọdụ ọkụ dị ala.
• Headphone interface for noise reduction in noisy environments.
• Battery polarity test function (9-60V).

4.1 Ịchaji batrị

Both the Transmitter and Receiver are equipped with rechargeable lithium-ion batteries. Use the provided charging cable to charge both units before first use and whenever the battery is low. The Power indicator LED will show charging status.

Figure 2: Both the Transmitter and Receiver units can be charged using a standard USB power source.

4.2 Connecting the Transmitter

To trace a wire, connect the transmitter to the wire using the alligator clips. Ensure a secure connection.

• Connect the red alligator clip to the wire you wish to trace.
• Connect the black alligator clip to a reliable ground source. For underground wires, this typically means a metal stake driven into the earth.
• Ensure the wire is not live and has no voltage exceeding 60V DC.

5.1 Powering On and Function Selection

• Nyefe: Slide the "Cable Scan" switch to the "Cable Scan" position to activate the tracing signal. The Power indicator will light up.
• onye nnata: Slide the On/Off switch to the "ON" position. The Power indicator will light up.

5.2 Wire Tracing

To locate and trace wires:

1. Ensure the transmitter is connected and powered on in "Cable Scan" mode.
2. Turn on the receiver. Adjust the "Signal Sensitivity Adjusting Switch" on the receiver to an appropriate level. Start with a lower sensitivity and increase as needed.
3. Hold the receiver with the T-shaped probe near the suspected path of the wire.
4. Move the probe slowly across the area. The receiver will emit a sound, and the signal strength will be indicated.
5. The sound will be loudest when the probe is directly above the cable and at a 90-degree angle to it. This indicates the target cable is perpendicular to the probe.
6. When the probe is parallel to the cable direction, the signal will be weakest or absent.

Figure 4: Visual guide on how to interpret signal strength and probe orientation for accurate wire location.

The detection range is typically up to 2-3 feet deep and 1000 feet long, though depth can vary based on soil conditions and wire type (e.g., 1-2 feet in steel/iron/PVC pipes).

5.3 Cable Break Detection

To detect a cable break, follow the wire tracing procedure. The signal will significantly weaken or disappear at the point of the break.

5.4 Short Testing

To test for short circuits:

1. Clamp the alligator clips of the transmitter to the exposed parts of the two wires you want to test.
2. Slide the transmitter switch to the "Battery Test" position.
3. Observe the "Status" indicator LED on the transmitter:
   • If the "Status" LED is na-egbuke egbuke mgbe niile, it indicates a short circuit.
   • If the "Status" LED is na-egbuke egbuke, it means there is no short circuit.

Figure 6: How to perform a short circuit test using the transmitter's "Battery Test" mode.

5.5 Battery Polarity Test (9-60V)

The transmitter can also test battery polarity:

1. Connect the red and black alligator clips to the positive and negative terminals of a 9-60V battery, respectively.
2. Slide the transmitter switch to the "Battery Test" position.
3. Observe the "Status" indicator LED:
   • If the "Status" LED is na-egbuke egbuke, it means the red clip side is the positive terminal.
   • If the "Status" LED is na-egbuke egbuke, it means the red clip side is the negative terminal.

5.6 Iji ọkụ ọkụ LED

The receiver has a built-in LED flashlight for use in dark or low-light conditions. Press the "Push for Light" button on the receiver to turn the LED on or off.

Figure 8: The receiver's LED flashlight provides illumination for working in dim environments.

5.7 Noise Reduction with Headphones

For noisy environments, you can plug headphones into the receiver's headphone interface to better distinguish the tracing sound. This helps in isolating the signal from ambient noise.
